STM32L0xx is low cost and ultra low power ARM® Cortex™-M0+ 0.93 DMIPS/MHz at 32 MHz maxThis new group of MCU is suitable for battery applications, it also reach modern security request thanks to AES 128.The main applications are: metering, medical, wireless security systems, home automation, etc.

Enhanced features:

Ultra low power consumption

Some peripherals can function on their own with the rest of the MCU and peripherals are OFF

Pin to pin compatibile with the STM32L1xxx (CORTEX M3 - Ultra Low Power).
Larger temperature range functionality: -40°C up to +125°C
Up to 24 capacitive sensing channels supporting touchkey, linear and rotary touch sensorsAutonomous Peripherals – Some peripherals can function on their own with the rest of the MCU and peripherals OFF

Low-power Pulse counter

Independent 16-bit timer, available also in Stop modePulse counter with no clock running or clocked by LSE, LSI, HSI, APB. It is able to wakeup the system from Stop mode.Programmable digital glitch filterEncoder mode

Equipped with a low-power UART
(LPUART), STM32L0 MCUs enable your application to stay connected at
outstandingly low consumption levels.
The LPUART can run on a low-power clock while the device is in a
power-saving mode and wake up the system upon a received frame event or
an address match.
To support engineers in squeezing the last nanoampere out of their
designs, a new application note (AN4635) is available which –
complemented by the X-CUBE-LPUART software examples – guides you
towards the optimum use of the LPUART with the help of numerous case
studies.
